Abstract

A method and apparatus for detecting synchronization signals. A chip for detecting a synchronization signal generated based on one of a plurality of sequences generated by a sequence generator, the chip comprising a memory and a processor connected to the memory may be provided. The processor may be configured to: receive a synchronization signal; perform a first descrambling of the received synchronization signal for the first sequence by multiplying the received synchronization signal with a first sequence from the plurality of sequences ; performing a second descrambling of the received synchronization signal for a second sequence from the plurality of sequences of the received synchronization signal by changing the sign of at least one element of the descrambling sequence of the first sequence, wherein the first The second sequence is the complex conjugate of the first sequence.

Description

technical field [0001] The present disclosure relates to methods and / or devices for detecting synchronization signals. Background technique [0002] In wireless communication systems, synchronization signals are used to detect or synchronize devices. A synchronization signal transmitted by one device can be detected by another device, and another device that has received the synchronization signal can identify the one device that has transmitted the synchronization signal. In a mobile communication system such as Long Term Evolution (LTE), a base station may broadcast a synchronization signal for synchronization with a user equipment (UE). In addition, UEs may also send synchronization signals for direct communication with other UEs. [0003] Some communication standards, such as LTE-based Narrowband Internet of Things (NB-IoT), may use synchronization signals combining Zadoff Chu (ZC) sequences, Hadamard matrices, and cyclic shifts. In this case, to detect the synchroniz...
